Dynamics and Extremes of Open Ocean Non‐Thermal <i>p</i> CO ₂ Time Series

Abstract The dynamics of the ocean partial pressure of are driven by both thermal and non‐thermal forcing. The contributions of these two components can be decomposed following the methodology of Takahashi et al. (1993, https://doi.org/10.1029/93GB02263 ), Takahashi et al. (2009, https://doi.org/10.1016/j.dsr2.2008.12.009 ). This method has been applied to in situ open‐ocean data from 17 fixed‐position buoys, allowing for an Eulerian monitoring of this scalar. The effect of non‐thermal processes on dynamics was investigated through probability density function (PDF) and PDF quotient analyzes, which revealed their importance, particularly in relation to extreme values (relative to their distribution). This emphasizes the importance of high‐frequency monitoring for carbon budget estimations, even in the open ocean, despite these ecosystems being less variable than, for example, coastal zones.
